First time for me missing it for a long time. It's pretty low key, but the people are great. Have fun!

I'd add that the people advocating most for these things might not understand the last part (what is of value to scientific research) very well.

Higher density of physicists? 😜 Observation holds for more hardware-y people, but mathematicians seem maybe more comfortable with AI - just depends on which population you see.

I got to visit the early access system for NERSC’s upcoming Doudna supercomputer. A TALL order of GB200s. Surprisingly noisy. #HPC

As hybrid #HPC + #AI + #Quantum workflows become more prevalent, orchestration of complex systems is becoming a key component of successful deployment. Looking forward to accelerating these capabilities for the open-source community.

I wrote up my notes from #SC25. Have a look: blog.glennklockwood.com/2025/12/sc25... I’ll keep picking away at the editing, but would love to hear more from others about what stood out to them. I wasn’t at the conference itself as much this years as in the past, so I know I missed a lot. #HPC

To be chosen to participate in the design of the next iteration is a massive honor for us. Through this partnership, we aim to develop a scientific discovery ecosystem based on the full integration of simulation and AI. We hope this work will benefit not only Japan, but also researchers worldwide.

Having watched engineers do the hybrid HPL run on Trinity, you should be sure to give anyone who attempts it lots of love (and a raise 😄)

Dan Ernst @ernstdj.bsky.social · 19/06/2025

There are none installed so the numbers would be the same. 😋 Once they come, they could try to do a hybrid run, but it would be an enormous pain to do and not much upside.

Same here. I came to social media to try to teach people things once in a while. You've always been happy to amplify whomever is helping others grow. #IamHPCGuru should be a rallying cry for giving new points of view a fair shake.

I think the best warmup for #ISC25 is a leisurely stroll through the botanical gardens across the plaza from CCH.

This is a great article that explains the philosophical innovations behind NERSC’s new supercomputer: science is not just about batch jobs anymore. Draw the good ideas from AI infra advances into #HPC as possible. Definitely worth reading. Also, they’re using GPFS instead of Lustre(!)
